Ok, you will need to have the vehicle computer reprogrammed at your local GM dealer.Here is info
08-06-04-037: Malfunction Indicator Lamp (MIL)/Check Engine Light On, DTC P0606 Set (Reprogram ECM) - (Jul 16, 2008)
Some customers may comment that the check engine light is on.
Upon investigation, the technician may find DTC P0606 set in history or as current.
Current ECM calibrations can't compensate for the difference between the expected throttle position and the actual position.
An updated calibration for the ECM has been released to address this concern. Reprogram the ECM with updated calibration files using the TIS2WEB Service Programming System (SPS) application. As always, make sure your Tech 2® is updated with the latest software version.
